The natural garnets from chromite ores associated with pegmatoid pyroxenites of Sangalyk area (Uchaly ore district, southern Urals, Russia) were studied by means of micro-Raman spectroscopy. The compositions of these garnets were close to ugrandite, an isomorphous intermediate group of uvarovite-grossularite-andradite, X(3)Y(2)(SiO(4))(3), X = Ca(2+), Y = Al(3+), Fe(3+), Cr(3+), according to Raman spectra and X-ray microprobe analyses. An assignment of most of the observed bands in visible and near infrared Raman spectra is reported.
通过显微拉曼光谱法对俄罗斯南乌拉尔乌恰利矿区桑加利克地区与似伟晶辉石岩有关的铬铁矿矿石中的天然石榴石进行了研究。根据拉曼光谱和X射线微探针分析，这些石榴石的成分接近钙铬榴石-钙铝榴石-钙铁榴石的同构中间组——钙铝榴石，化学式为X(3)Y(2)(SiO(4))(3)，其中X = Ca(2+)，Y = Al(3+)、Fe(3+)、Cr(3+)。本文报道了在可见和近红外拉曼光谱中观察到的大部分谱带的归属。
